Notes

Those 7 pin connectors seen on some PC graphics cards are non-standard connectors for carrying S-video.

Generally the first four pins on those 7-pin connectors on the same places as the standard four pin S-video connector have practically always the same fuctionality as those pins in S-video connector.

The other three pins can have then some extra signals which are not part of S-video (usually some pins of those carry composite video and some control signals, but the use of those three extra pins vary quite much).
